How to make graph not show, only indicator?

So, for example, in the included sample Heiken Ashi of MT4 : if I want only the Heiken Ashi to show and not the graph, how do I accomplish this manually, and within the indicator/EA?

There must be a better way but I have done this as follows:
1. Make your chart "Bar chart" and not Candlestick (button on top of MT4)
2. Right-click on the chart, choose "Properties"
3. Select the tab "Colors"
4. For "Bar up", "Bar down", "Bull candle", "Bear Candle", "Line graph" select the same color as "Background color".

Slightly fewer steps than Kostas' solution:
1. Choose Line Chart (press Alt-3)
2. Press F8, set Line Graphs color (on Colors tab) to None
