Click on the Colored Shapes Option button in the Operators list.

	

The Options box opens when the Options button is selected.

    

Click the Scale Colors button at the bottom of the Colored Shapes Options box.
Enter 1.0 in the last Data Value field displayed in the Scale Colors box (field #10).
Click on OK to accept the scaling and remove the Scale Colors window.

Entering values in the Data Value fields changes the color scaling of the current operator. In this example, the data has values as high as 70, but values near 1 are considered significant. Automatically scaling this type of distribution makes the low values hard to differentiate from the zero values. Setting the light-blue (#10) field to 1.0 skews the scale towards the lower end, making it easier to differentiate low values from each other (values between 0 and 1 were pr eviously nearly identical). The values on the color bar in the graphics window change to reflect the new scaling.

Move your mouse to the Clipping Values section of the Colored Shapes Options box and enter 1.0 in the Lower Value entry field.

For this simulation, 1.0 ppb was defined as the lowest detectable level of benzene.
