GUI chart (Highcharts - Open Source Graphing Library)
Creates object of the PmaPanel
type and object of the PmaWebDir
There is a script onPageModify
in the PmaWebDir
object that calls the methods graph
. The "graph"
method creates the html
page that contain links to Highcharts open source
application for chart rendering. The "sourcedata"
method prepares the source data to be displayed by the chart.
In the "sourcedata"
method, the data is prepared into a specific json
format that has its specification. The first row represents the header where the first column is time and in the following columns the names of variables. The following rows and columns contain the data to be displayed. The dimension of the data set is defined by the variables nRows
In the "graph"
method, it is possible to define the appearance and labels in the chart:
- in the sections title:, subtitle and yAxis, there are the main title, secondary title and Y axis label.
- in the section series:, there is the line width setting, rendering type setting, colors and transparency for each chart line.
The description and additional options can be found in documentation: https://api.highcharts.com/highcharts/
The open source
application is linked online so the chart rendering will be possible only if the Web client can connect to the internet.
