Second, the flat colored horizontal line will start moving to plot the value of the strength as measured in milli-gravities. The horizontal line's movement is based on the micro:bit acceleration in Magnitude or Strength. Second, the horizontal line will move to plot the value of the strength as measured in milli-gravities.

Use the Recommended Charts command on the Insert tab to quickly create a chart that’s just right for your data. ## 9.
* Select the data that you want to include in your chart. The black lines should appear directly beneath the colored lines. The black lines measure the micro:bit acceleration. And the colored lines measures micro:bit simulator acceleration.

* On the Recommended Charts tab, scroll through the list of chart types that Excel recommends for your data. Every time the micro:bit moves in any direction, you generate data points that can be reviewed in Excel later. The more attempts to move the micro:bit, the more data to be reviewed in Excel.
Click any chart type to see how your data will look in that format. ![](/static/mb/lessons/seis_challenge04.png)
When you find the chart type that you want, click it, and then click OK. We want to select the chart called Line. A line chart is used to display trends over time. We will use the line chart because there are many data points over time.
Tip: If you don’t see a chart type that you want, click the All Charts tab to see all of the available chart types.

* Use the Chart Elements, Chart Styles, and Chart Filters buttons next to the upper-right corner of the chart to add chart elements like axis titles or data labels, to customize the look of your chart
