To add extra space to a chart to make trend line projections, you need to add extra bars to the right of a chart. Here's how to add extra space in SharpCharts.

1. Go to the Chart Attributes section located below the SharpChart.
2. Add the number of rows you want to the right in the Extra Bars box.
3. Click the Update button.

Note: The Extra Bars option is unavailable if you use the “Select Start/End” option in the Range dropdown.

This feature is available to all subscribers and free users.

**You can add up to two years of extra bars to your chart. These extra bars are included in the overall chart data limits, which you should remember when configuring your chart. For example, if you're a free user, you're limited to a total of three years of data. So, if you add two years of extra bars, you can only display one year of actual price data on your chart.

The above chart is an example of what a one-year chart with 500 “Extra Bars” looks like.
