6.2 Handling missing values in the scatterplot chart
The Dynamic Scatterplot chart handles differently the missing values of numeric fields depending on whether the numeric field with missing values is selected in the plot axes or in the color scale selector.
If the values of any of the fields in the fields selectors are missing for some instances in the current sample, a label will inform about the number of missing values found in the sample.
If the values of any of the fields in the axes (or both) are missing for all the instances in the sample, a message will appear informing about it and no points will be drawn in the plot. You can try to request another sample to get some new data.
If only part of the instances in the current sample have missing values for any of the fields in the axes, the points representing those instances will not be drawn.
Figure 6.5 Dynamic scatterplot missing values in axes If the entire sample has missing values in the field chosen as color selector, you will see a border but no filling for the circles that represent your sample data. If only some instances have missings, the circle will be filled with the regular background color and also a line texture.
