I want to plot a spline chart (logarithmic scale) based on inserted data in QFIELD app

[geesaraw]

I have two virtual fields that generate a sequence of values separated by commas.
a sample dataset looks as follows,
X = 2,4,5,6,8... etc
Y = 10,20,30,40... etc
where these values are generated based on inserted data in the field.

As QML widget does not directly support spline charts yet (Only Pie chart and Bar Chart), I am seeking for an option to plot these data while in the field using QFIELD app. I want to view the graph at the field hence it should be dynamically updated based on entered data.

What is the best method to plot the mentioned sline graph Y vs X (both axes in log scale) ?

I tried plotly in html widget, even though it is shown in QGIS attribute forms, it is empty in QFIELD.

Please help
