Chart

Adding a chart

Charts have two properties which are needed to create them chart_info and chart_build_details. The easiest way to add them to a form is via the client code, so that you can customize their heights and add them to a flow panel grid. The form name is GenericChart and they have been designed to be able to use them without other dependencies.

Chart_info

chart_info is a dictionary that must contain the following data:

• chart_number - this is used when the chart is created to make sure that the chart has a unique id, so that it doesn't conflict with other charts being created. The charts' ids take the form generic-chart + chart_number.

• labels - this is a list if str that will be the labels of the x-axis of the chart.

• data - this is a list of int or float which be the x-axis data.

Examples of adding these are available with all templates that have charts on them as well as databases that contain synthetic data to illustrate the type of data required.

Chart_build_details

In MainModule there is a function called get_chart_build_details which takes as a parameter the chart_info and returns the chart_build_details variable. This variable is consistent with the dictionary syntax that is needed to create the chart in Javascript, so there isn't a need to change this unless you want to customize the charts, but then you would need to know how the Javascript syntax works.
