# Options on the X-Axis and the Y-Axis tabs of the ME Chart Control Properties dialog box

The X-Axis and the Y-Axis tabs of the ME Chart Control Properties dialog box show the same options as follows.

Options | Descriptions
Min / Max value options | Specify the minimum and maximum values.
Automatic (Best fit based on data) | If select this option, the lowest data reading serves as the minimum value and the highest data reading serves as the maximum value. As the chart acquires new data, the x-axis or y-axis may re-scale automatically to fit.
Custom | Select this option to specify the minimum and maximum values that serve as the x-axis or y-axis scale. Specify a fixed value or control the value by a tag such as X_Axis_Min or X_Axis_Max.
Display options | Specify how the x-axis or y-axis shows at run time.
Display axis label | Select this check box to show the horizontal or vertical axis label on the chart. Specify a fixed value or control the value by a tag such as X_Axis_Label or Y_Axis_Label.
Display scale | Select this check box to show scales besides the x-axis or y-axis. Enter a value from 0 through 8 to configure the number of decimal places included on the axis. If the value is set to a non-zero value, numbers cannot be accurately converted to octal or hexadecimal. To provide accurate data, the chart shows the numbers as decimals, even if Octal or Hexadecimal is selected for Chart radix on the General tab of the ME Chart Control Properties dialog box.
Display gridlines | Select this check box to show the horizontal or vertical grid lines on the chart. For Major Gridlines, enter a value from 0 through 30. For Minor Gridlines, enter a value from 0 through 10. Click the color square to configure the color of the grid lines.
