Data Save Control Issue

[workingbuddy10]

I wanted to integrate the Data Save control feature in my app but there is an issue while restoring the drawings/indicators.

Though properties are getting saved in the local storage but when I re-open the app tab after closing it, I am not getting the option of restoring the drawings/indicators.

Image 1:

Image 2 ( rectangle series is there & saved in local storage) :

Image 3 (After re-opening the app tab again, I am not getting the option) :

And even though there are Two drawings in the local storage but when I re-stored it. It displayed only the last one.

• I made the triangle series earlier, then I close the tab and again re-open it. After that I have drawn the Fibonacci series.

So the main issue is when I re-open the tab I am unable to re-store the drawings/indicators even though details/data is stored in the local storage.

Lastly you can see in the images, the pop-up of opening data save control is opening below the indicator control.

Does this happen in all amCharts demos, or just locally?

I just tried the workflow you described here: https://codepen.io/team/amcharts/pen/BaMXwQZ/f0883e6dd0d9cb1f1e56aba39443e0d7

Works fine.

Finally, which browser are you testing with?

[workingbuddy10]

I am using Chrome browser.

So the main use of storing the data of the drawing/indicators is that we can retrieve the data again after re-opening the tab or re-loading the tab. But it is not happening.

Sure no issues!

Secondly there is should be mapping with the product name too!

Let's say, in my app I have given the option of multiple layout. A user open the chart of Google in 1D format in 1x1 layout ( single chart) , and then switches to 1x2 layout ( 2charts) and again plots the same chart ( i.e. Google in 1D format) so he should be able to retrieve/restore the drawings which was was made in 1st chart.

In the below image, I have plotted Index_SNP in 1D format and then I switch to 1x2 format and again I plotted the same chart. Now I am unable to access the drawings which I made in first chart, even though the product is same.

I hope it makes sense, When the product is same then user should be able to access the drawing/indicator data in multi-chart layout too. @martynasma
