It would be good if the followings are possible.
Suppose that a bar chart is specified as the combo chart.
At that time, the height of one or two bar charts may be significantly
higher than the values of other bar charts.
I'd like to omit the part between those one or two bar charts so that
the height is a little higher than the height of the other bars.
Current status
It is not possible to omit the part between the bar charts.
Therefore, I have to specify a small value for the maximum display range
of the Y axis.
Bar charts that are taller than the display range will display
a diagonal line at the top to indicate omission.
However, the scale of the large bar chart cannot be displayed.
Therefore, I set the [Bar Label] to display the value on the bar chart.
