How to implement export to excel functionality for the ag grid having sparkline chart (from highcharts library) integrated?

I am having sparkline charts integrated with ag grid and it's working as expected but as per requirement, I also have to implement export to excel functionality which should export all the row details from ag-grid along with the sparkline chart details.
Things tried:
I have tried most common way to export the details from ag-grid and which is working as expected. Things that I can see while exporting the excel sheet is only the data points values (numbers) that I have passed to plot sparkline chart per row instead of exporting the HTML of the chart.
With the export of data values only, I don't think it gives much detailed information to the user.
Expected Outcome:
I want to export the ag grid details along with the sparkline charts HTML contents. That simply means, if the contents are exported from Ag-grid having sparkline chart, the actual sparkline chart should be exported instead of data points used to plot charts.
In common terms, I want to picturise the sparkline chart as it is in the exported sheet instead of showing values in form of numbers
Is there any way to export entire chart which is already plotted on web app, and I want same to be presented into excel sheet for better representation of sparkline charts when export to excel should happen (highcharts library)?
Note:
I have used ag-grid and integrated sparkline charts from highcharts library. The entire functionality is implemented with help of Angular 7

Plot the ECG labels and the ECG using Flutter web

I am trying to plot both the labels and the ECG using Web Flutter. ECG plotting is happening properly but not the annotations. Can someone suggest me something for this? It should look something like this.
Found a library call syncfusion. It shows how to add multiple annotations. But the annotation that I am using is a list.
We have created a simple sample by using annotations in the chart. We have provided two annotations in the annotation list such as high and low texts for the high and low values in the chart. The two annotations are provided in the annotation property available in the chart which takes a list of type CartesianChartAnnotation.
The sample for reference can be found below.
Sample
And, we have analyzed the mentioned query ECG plotting is happening properly but not the annotations, but we are not sure of what exactly you are conveying. So, we request you to provide more detailed information for this query so that it will be helpful in providing the solution sooner.

which is an alternate chart for sankey diagram in tableau

I have been trying to visualise a sequence chart(flow) in tableau using sankey chart. is there any workaround for sankey? if there is an workaround suggest a good visualisation.
You can use heatmaps with source/ target in rows and columns and the flow value be represented in the cell.
Alternatively, you can stick with tableau for sankeys. I have done that and it adds immense value to develop overall storyline.
