### Charts

This
section contains components used to create, display and edit
charts such as histograms and scatter plots, and it will explain how to
create and edit the style of the types
of charts supported by Terralib.

The supported charts are:

- Histogram:
A
histogram is a graphical representations showing a visual impression of
the distribution of data. It is an estimate of the probability
distribution of a continuous variable. A histogram consists of tabular
frequencies, shown as adjacent rectangles, erected over discrete
intervals (bins), with an area equal to the frequency of the
observations in the interval.

- Scatter:
A
scatter plot is a type of mathematical diagram using Cartesian
coordinate to display values for two variables for a set of
data. The
data is displayed as a collection of points, each having the value of
one variable determining the position on the horizontal axis and the
value of the other variable determining the position on the vertical
axis.

To interact or change the chart style there are two general guides:

- Chart Display:
The interface used to display a chart and interact with the plotter area.

- Chart Style:
It is used
to configure/change the chart style, such as the font of its title, the text on its labels, the
background color, among other properties.
