LineChart
Introduction
Linechart
is a Supervisely widget that allows for visualizing data as a line chart. It supports data in pandas dataframe format or a Python list of dictionaries with a specific structure. This widget could be considered an advanced version of a LinePlot
widget with the support of ApexCharts library.
The widget allows for customization of the chart title, axis titles, and color scheme. Linechart
also supports zooming, panning, and downloading the chart as png, svg, or csv. Additionally, it can detect clicks on data points and respond to them through Python code
