extent on horizontal bar chart

[ronhud]

I have a horizontal bar chart arrived at by following a small number of posts  on this forum.  I am at the stage where the correct labels are shown on both axis but the visible data on the chart is only a small proportion of the loaded data - that is it appears like a very deep zoom.   How can I ensure that the total data is shown within the 'viewport'?

Please post a small project showing the issue.

Thanks for responding I will prepare a project.    The X axis is based on the volume of shares at different price levels, the  lowest number is 57072236 and the highest 118543400 - might such a large range be the cause of the problem?

Just realised (feeling foolish) that clicking the RH mouse button changes to showing all the data in the viewport.    Thanks again for the response.
