Place the indi onto the chart.
Drag the border between the primary window and also the indi window to the very top of the main chart window.
The indi must now fill out the entire (or nearly) of that chart.

If you cannot see the candles at the indi window it will be because the scale is wrong. You would then have to correct the indi window maximum and min values to accommodate the correct values.
(Right click on chart/ indiors/common tab/ put tick in Fixed Minimum Maximum boxes/ adjust the worth )
