A column chart is a data visualization where each category is represented by a rectangle, with the height of the rectangle being proportional to the values being plotted. The column charts are of two types.
Basic Column Chart
Stacked Column Chart
In QMetry, the Advance SQL Query provides an ability to generate both the charts as with the required values; let’s understand how both types of column chart can be generated by writing a SQL queries in detail.
Basic Column Chart
Stacked Column Chart
Let’s take an example of a Column Chart report.
Report : Generate a chart that displays the Count of the test case execution per release in a project (i.e. Count Of Test Case Execution Per Release)
SQL Query
Count Of Test Case Execution Per Release
SELECT
testexecutions.releaseName as "Release Name",
testexecutions.tcExecutionStatusName "Exec Status",
COUNT(1) as "Execution Count"
FROM testexecutions
WHERE testexecutions.projectID in (`@Filter.project`)
AND testexecutions.tcExecutionStatusName NOT IN ("Not Run")
GROUP BY testexecutions.releaseName, testexecutions.tcExecutionStatusName
Apply the Filter
Query Output
By default, it gives you output in tabular format. You can modify the output format. You can switch to the available chart types from the table. In our case, we will switch it to the Column Chart.
You can adjust the Columns based on the requirement to X-Axis, Y-Axis and Cross Tab.
X-axis always holds a single Test entity field with any value.
Multiple Test entity field on Y-axis creates a stacked chart; Y-axis always contain fields with numeric values.
Cross tab field will help to create a Group Stacked chart.
Once you get your desired report, you can save the report as a Gadget by clicking on the Add Gadget button.
Once you save the gadget, it will be available in the QMetry Custom Gadget section > My Gadget tab.
