Example file with chart

I cannot reproduce this. 

The numbers in the chart does get updated. Once you change the data in the source table, save the file, close and reopen again, the Chart is updated with correct values.

In 5.2 the chart updates at once after changing of number in table and moving of cursor out of table. Without any additional actions a-la save/reopen.
Now, in LO 6.3 I can update chart if I enter in chart edit mode and then exit from it at once.

I bisected it

After following steps from Comment #5 

I can confirm that the bug is present in

chart gets updated in both versions once you will change the data in source table and save it as .odt and reopen it

After a quick look at the source code, this behavior seems like the result of a design decision to improve performance, but not a random regression.

OTOH, we could improve the situation, thus changing it to enhancement.

Some random thoughts on the ways to improve:
- Put in a timer, so the data update doesn't get triggered during a regular scrolling (Currently, we do the refresh on state change, so the chart gets updated if you double click it)
- Make it optional by putting a checkbox to settings to enable/disable caching chart data (should be enabled by default IMHO)

The menu item Tools -> Update -> Charts

does not seem to have any effect. LO Windows 10 7.0.4

The appropriate menu item to update the chart does not work so this portion of the problem appears to be a bug.
