Zooming in to a chart
You can zoom in to a chart to see details of displayed data. Chart gadgets and charts in BIRT documents support zooming on the x-axis, y-axis, or both at the same time. Zoom is enabled by the BIRT dashboard developer.
To make an x-axis zoom, select a start point on the x-axis, drag the mouse to the end point, and then release the mouse button. Figure 4‑67 shows an x-axis zoom.
