XY plotter in WebIQ

[bclapperton]

Does WebIQ have an XY Plotter widget? I want to plot an array of X values vs an array of Y values.

WebIQ has a Trend widget for displaying real-time data and also some historic data. However, we don't like to reinvent the wheel so for plotting arbitrary data you can use the open-source JavaScript library ChartJS for example (see "Line Chart" here: https://demo.smart-hmi.com/chart-demo/) You can download this demo and the corresponding widget we created for this library for free in our customer area.

For our template we created a WebIQ package based on plotly (a common js package under MIT license), with the following features:

• Record data in PLC, create a json with the data to send it to WebIQ (with PLC example code to adapt)
• Package cxPlotly (which uses package-plotly) containing widget cx-osci

For more infos see template documentation and PLC example source code.
