Description intmianol 2019-01-21 14:19:04 UTC 
Description:
Add an option to Chart > Data Ranges... window, in order to turn off live preview, because it is very slow.

Actual Results:
When I change the data ranges of a chart, it is updated instantly as I type. There is not option to disable this.

Expected Results:
When I change the data ranges of a chart, it should *not* be updated instantly as I type. There should be an option to enable that.


Reproducible: Always

Sounds reasonable. Sometimes you have a complex diagram requiring the chart range to setup and with many data it takes some seconds to redraw the preview.

In the current dialog, the checkbox has no good place within the tabs; it has to be placed next to Help. There is a design proposal [1] how to revamp the chart dialog (maybe a GSoC project) where the preview is shown in the dialog (like we do at other places). And it could be simply a checkbox that disables this preview.

In chart2/source/controller/dialogs/tp_DataSource.cxx method RangeModifiedHdl the function updateModelFromControl() does the work. However, without this function the modification is not stored and you cannot change data series A then B. I see no simple solution.
