Drawing in the Artist Window

After an Artist window has been inserted using the Insert menu Artist Window command, a curve may be drawn simply by dragging the mouse through the window. The following entries in the Artist window control the scaling and type of graph that is drawn:

• X Min and X Max. Specifies the X-axis scaling for the drawn graph.
• # Markers. Sets the number of markers that will be drawn as you drag across the min-max range of the graph. Markers allow you to drag the points on the curve to change its shape.
• Curve Type. Specifies the type of curve that will be created, where Density is a probability density curve, Cumulative Asc. is an ascending cumulative curve and Cumulative Des. is a descending cumulative curve.
• Marker Drag Style. Specifies whether markers will be connected with straight lines or curves when they are moved.

If you are drawing an ascending cumulative distribution (as specified in the Curve Type option), you will only be able to draw a curve with ascending Y values, and vice-versa for a descending cumulative curve.

When you have completed a curve, the end-points on your curve will be automatically plotted.

After drawing a curve, you may want to "drag" one of the markers to a new location. Simply click the left mouse button on the marker and, while holding down the button, drag the point to a new location. When you lift the button, the curve is redrawn automatically to include the new data point.

You can only move data points along the Y-axis, and you cannot drag points outside the axes. You cannot modify the positions of the end points.
