Mekko Graphics allows the capability to change the axis scales for both bar/area/line and bubble/scatter charts. They can be automatic or manual.
1.Right click on the Axis and choose Format Axes from the Axis Context Menu
2.The default scale is computed, meaning that Mekko Graphics computes the scale based on your data and the type of chart you are creating. However, you may customize your axis scale by clicking the Manual Scale radio button. Once you click the Manual Scale button, the minimum, maximum, and tick interval fields become enabled, allowing you to enter values. The values are defaulted to the computed values for that chart.
Select the minimum and maximum axis value as well as the tick interval (the interval between axis values displayed).
Reference Bubble - Allows you to format the relative scale of the reference bubble. You may select the default calculated value or choose a manual value for the reference bubble. You may also choose to hide the reference bubble in your chart, or simply hide the label.
You may also perform the same functions by clicking the Axis button in the Edit Chart toolbar
