That's really tough, but you can try for alternate options. Some suggestions are: to enable scroll bar to your x-axis. Go to chart properties >> Presentation >> Chart Scrolling >> Enable x-Axis scrolling >> and write 10-15 for display of bars.
Or limit your results by using rank, and then i show only values based on min and max rank.
Or you can restrict some values using "Dimension Limits" tab of Chart property.
