ColorA 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 ScaleAuto 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.
