Problem with old/new Charts

Problem with old/new Charts

Dear Zoho guys.

I'm concerned about the following issues I'm facing in a Combination Stacked Chart:

Issue 1:
When I use the OLD Graphs in a combination stacked chart, the bars are shown stacked but the line are shown in the same scale.
Whet I turn into the new Graphs the bars are still shown stacked and the lines are ALSO shown stacked (here is my problem, I need to show both lines under the same scale):

Issue 2: When I try to show numeric values in a chart, everytime i Try to show values with 0 decimals, the value shown has 7 or more decimals.

Any Help????
Thanks in advance for your quick support.
