Line column charts
The line column chart combines the column and line charts. Your search needs at least one attribute and two measures to be represented as a line column chart.
Line column charts display one measure as a column chart, and the other as a line chart. Each of these measures has its own y-axis.
You can enable a shared y-axis by clicking the dropdown menu icon next to the y-axis label and selecting Group for both measures.
