Issue: In case of zero filling in stack bar chart for calculating the height of the empty bucket
we are using the 1% of maximum value of the yAxis field, which fails when the yaxis values are
very high like databaseusage or memory usage etc;

Fix: Instead of using the yAxis field value, we are calculating the based on the height of the
