Reports: Creating a New Chart
Spiro Reports provides an easy to use drag and drop interface to create charts fast & easy. You can create various types of charts including Bar, Line, Pie,Stacked, Scatter, Area, Combination, Funnel, Web and 3D charts by simply dragging and dropping the required columns into the respective shelves in the design area.
You can change the chart type any time without having to recreate it. You can also apply the appropriate aggregate functions on the columns to calculate and summarize data the way you want it.
To create a chart, follow the steps given below:
- Open the reporting database in which you would like to create a chart.
- Click New button in the top left corner of the database and select New Report.
- In the New Reports tab that opens, click Chart View.
- In the Select Base Table dialog box that opens, select the required table in your database on which you want create the chart and then click OK.
- The Chart Designer opens as shown below.
You can also create new chart by opening the corresponding data table on which you want to create the chart and invoking New > New Chart View option in the toolbar.
- You can also create charts over a Query Table following the same instruction given above.
On the left hand side is the Column list pane, listing all the columns available in the table. On the right hand side, you can see the Design Area with shelves to drop the columns and a Preview area below to view chart created.
You must drag and drop the required columns listed in the Column list pane into the respective shelves inorder to create a chart. You can also select the check box adjacent to each column listed to auto place the columns into the appropriate shelves. After dropping the columns click on the option Click here to Generate Graph to create the new chart.
Given below is a brief description of each of the shelves in the Graph tab.
- X-Axis: Column dropped in this shelf appears horizontally across X-axis.
- Y-Axis: Column dropped in this shelf appears vertically across Y-axis. You can drop multiple columns in this shelf to create charts with multiple Y-axes.
Here is an example to illustrate how to create a simple bar chart. We will create a chart to display the Sales trend across all years using a sample store sales data. Drag and drop the Date and Sales columns to X and Y - Axis and click on the button "Click here to Generate Graph". You will notice that as soon as the button is clicked a bar chart will be created.
- Color: When a column is dropped in this shelf, the chart will be further categorized showing each data point in this column in different colors (different data series) in the chart.
Continuing the above example, if you want to create Date-wise Sales by Region chart, drag and drop Region column into the Color shelf. Now, the chart will be further categorized based on Region and each region will be assigned a unique color as shown in the below screenshot.
- Text: Includes the corresponding value of the dropped column as data label in the chart, according to the function applied on the column.
- Include columns for Tooltip: Includes the corresponding value of the dropped columns in the chart tool-tip, according to the function applied on the column.
Following screenshot describes how would a final chart would look like (in view mode) when Text and Include columns for Tooltip options are selected.
In Edit Design mode, you will notice that a menu appears on mouse over the top right corner of the Columns List pane. You can expand, sort and filter the list of columns using the options available in this menu. The available options are:
- Expand All and Collapse All: The 'Expand All' allows you to expand the field`s list, the 'Collapse All', collapses the table.
- Apply Sort: You can sort the column either by name or by type, you may also further sort it in ascending or descending order.
- Apply Filters: This option is useful when you need to filter the columns based on the data type.
- Show Involved columns: Lists the columns involved in creating the report.
Spiro Reports allows you to apply aggregate/categorical functions like Sum, Count, Average, Min, Max, etc., on the data columns to group and summarize data in charts. When you apply a function on a column, a single value will be returned which is derived based on the values in the column. The default function for a Numeric (including Currency) data type is Sum and for a Date data type is Year. If the data type of the column is string (Categorical/Dimension column) and not numeric, then the default function applied is Actual Values.
To change the default function applied, after dropping the column, select the required function (aggregate/categorical) from the drop-down list present on the column. Drop-down list displays all the applicable functions based on the data type of the column, as shown in the screenshots below.
String Data Type
Numeric Data Type
Date Data Type
For instance, if you want to plot Average Sales for each Month across each Region, select Average function from the drop-down list for Sales (Y Axis) column, Month & Year function for Date (X Axis) column and select Actual Values function for Region (Color column) and then click on the button 'Click here to Generate Graph'.
The following tables list all the functions along with the description of their functionality.
Numeric and Currency Data Types:
|Sum||Returns the sum of all the values in the column. The summation will be done at each category/group level shown in the report.|
|Maximum [Max]||Returns the maximum value in the column.|
|Minimum [Min]||Returns the minimum value in the column.|
|Average [Avg]||Returns the average of all the values in the column.|
|Standard deviation||Returns standard deviation derived based on all values in the column.|
|Variance||Returns the variance of the column.|
|Count||Returns the count of the number of values in the column.|
|Distinct Count||Returns the count of the number of distinct values in the column.|
|Measure||Treats the values in the column as a measurable numeric value. Returns each distinct value present as a numeric value to be plotted in the report.|
|Dimension||Treats the values in the column as a textual (categorical/dimensional) value. Returns each distinct value present as a text value to be plotted in the report.|
|Range||Groups the entire range of numeric values present in the column into multiple ranges.. e.g., if your data range is between 0 to 1000 then it will be grouped as 0 to 100, 101 to 250 ... 901-1000. You can also specify the custom range size to group the data using the Add New Range link. i.e.,if you set the range size as 50, then it will be grouped as 0 to 50, 51 to 100 ....|
Date Data Type - Actual Value Functions:
|Year||Returns all distinct year values present in the column. E.g.,2003, 2010|
|Quarter & Year||Returns all distinct quarter & year values present in the column. E.g., Q1 2010|
|Month & Year||Returns all distinct month & year values present in the column. E.g., March 2010|
|Week & Year||Returns all distinct week of the year values present in the column. E.g., W1 2010|
|Full Date||Returns all distinct dates present in the column. E.g., 1/1/2011|
|Date & Time||Returns all distinct date and time pairs present in the column. E.g. 01/12/2010 00:10:07 hrs|
Date Data Type - Seasonal Value Functions:
|Quarter||Helps identifying seasonal trends based on quarters present across all years in the column. E.g., Q1, Q2.|
|Month||Helps identifying seasonal trends based on months across all years. E.g., January, February.|
|Week||Helps identifying seasonal trends based on weeks across all years. E.g., Week 1, Week 2.|
|Week Day||Helps to identify seasonal trends based on weekday across all years. E.g., Sunday, Monday.|
|Day of Month||Helps identifying seasonal trends based on day of month across all dates. E.g., 1 to 31.|
|Hour of Day||Helps identifying trends across hours in a day. E.g., 0 to 23hrs.|
Date Data Type - Aggregate Function:
|Count||Returns the number of date values in the column.|
|Distinct Count||Returns the number of distinct date values in the column.|
String(Categorical/Dimension) Data Type:
|Actual Values||All the distinct values in the column will be listed.|
|Count||Number of values in the column will be listed.|
|Distinct Count||Number of distinct values in the column will be listed.|
When creating a chart, Spiro Reports provides advanced summary functions, apart from the basic functions such as Sum, Max, Min or Average. This allows you to summarize data values in that column based on the values in other columns. Using this you will be able to do some powerful calculations on a chart like running total of sales over years or calculate the difference in sales from the previous year etc.,
Following are the advanced summarizing options:
|Normal||Displays the calculated value of the aggregate function applied over the column. By default, this option will be selected.|
|% of Total||Displays the percentage of the grand total of all the data in the chart series.|
|Running Total||Displays data in successive data points of the chart as a running total, based on the selected Base Field.|
|Difference From||Displays the data in each data point as the difference from the value in the previous data point, based on the selected Base Field.|
|% of Previous Value||Displays the data in each data point as a percentage of the value in the previous data point, based on the selected Base Field.|
|% of Difference From||Displays the data in each data point as a percentage of differences from the value in the previous data point, based on the selected Base Field.|
|100% Group|| Displays the percentage of the data point value in total of the group, based on the selected Base Field. This will be useful while creating 100% Stacked Bar and 100% Stacked Area Chart.
When you create a chart for sales across years categorized by region, then using this function you could get the percentage of sales in each region as seen the example at the left.
|Moving Average|| Displays the calculated moving value of each data point based on the inputs you provide. The summary function selected will be taken as the base for calculation. You can perform sum, average, minimum and maximum calculation using this.
This will be useful to visualize the trend of your data. The example at the left illustrates the impression of your website vs. moving average of the impressions for the last 30 days.
The following screenshot illustrates a sample chart with different advanced summary functions applied.
After creating a chart, you can easily change it to another chart type by simply clicking on a button without changing the plotted data. For example, you have created a Bar chart, but then decide that you want the data to be displayed as a Pie chart. You can do this by changing the chart type using the toolbar or you can use Other Charts button on the toolbar.
Toolbar provides you with the options to choose between Pie, Bar, Stacked Bar, Line, Scatter and Table chart types at the top level. If you do not find the chart type that you are looking for, then click on Other Charts button in the toolbar and select the chart type that you want to apply from the Chart Options dialog box that appears. You can view a brief description of each chart type the bottom of the dialog box by clicking on the specific chart type. Notice that chart types that are not applicable/unsupported for the combination of columns that you are using to create the chart will appear disabled.
After selecting the required chart type in the dialog box, click OK.
