Chart Editor Dialog Box Description
The following elements describe the Chart Editor dialog box.
| Number | Component | Description |
|---|---|---|
 | Select Series | The Select Series field contains a drop-down menu that lists all the tags in the chart. You can select any of the tags listed. |
 | Type | Changing the Type changes the way the highlighted tag in the Select Series field displays in the chart. Type includes: Line, Area, Scatter, and Statistics. For more information, refer to Chart Type Options. |
 | Color | A different color is used for each legend in chart. You can change the line color for each tag on your chart or the line color of the bell curve in a histogram by choosing a new color from the 18 pre-existing colors or accept the color that the system provides. You can also use the Color option to change the color of the bins in a histogram chart. |
 | Auto Scale | Auto Scale allows you to enable or disable automatic scaling of your chart. When you disable Auto Scale, the system allows you to specify the minimum and maximum range of values for the chart to display. By default, the Y-axis scales to the low and high points found within the Historian data sample. To set your own scale, slide the icon to the right (it should turn gray) and enter your own low (Min:) and high (Max:) points for the Y-axis. |
