    Point Chart
    In This Topic

    Point Charts displays 1, 2 or 3-dimensional data as points in a Cartesian coordinate system. They are often used for XY and XYZ scatter plots especially when a large number of data points need to be displayed. Following is a description of the point chart settings:


    Sub Type - the following table summarizes the different subtypes of the point chart:

    Subtype X Dimension Type Z Dimension Type Data Requirements Description
    Series Categorical Categorical Y Shows series behind each other
    XY Scatter Numeric Categorical Y
    Besides the Y value, each data point has a X coordinate at which it is positioned.
    XYZ Scatter Numeric Numeric Y
    Besides the Y value, each data point has a X and Z coordinate at which it is positioned.

    Shape - defines the shape of the points. Possible values are: Bar, Cylinder, Cone, Inverted Cone, Pyramid, Inverted Pyramid, Sphere, Ellipse, Cross, Diagonal Cross, Line Cross, Line Diagonal Cross and Star.

    Size - controls the size of the point shape.

    Cluster Mode - controls whether the point chart uses clustering. Clustering works by identifying densely populated regions of data, which are later visualized by a single point. This reduces the number of visual points on the screen and therefore improves performance. When you use clustering the point series will not regard settings for markers, data points, individual fill styles and shadow. Possible values are:

    Auto - The area series uses sampling only when the number of data points is large.
    Enabled - The area series always uses sampling.
    Disabled - The area series does not use sampling. This is the default.

    Cluster Distance Factor - controls the maximum distance between two data points if they are to be merged in a cluster. Higher values for this property will diminish the number of visual points, but will decrease the precision of the cluster and vice versa.

    Drop Lines (X/Y/Z)

    Show - controls whether the drop line is visible

    Origin Mode - controls the drop line origin mode. Possible values are:

    Scale Min- drop line extends from the point value to the scale min value.

    Scale Max - drop line extends from the point value to the scale max value.

    Custom Value - drop line extends from the point value to the specified custom value.

    Origin - controls the second point of the drop line in case Origin Mode is set to Custom Value.

    Stroke Style - controls the stroke style of the drop lines.

     Automatic Data Labels Positioning
    The automatic positioning of data labels is the data point center.
     Automatic Legend Mode
    The automatic legend mode in all subtypes evaluates to series (e.g. the series is displayed in the legend).
