Data Plots & Best-Fit Curves

Use ListPlot to visualize data as a scatterplot:

In[1]:=

⨯

ListPlot[{1, 3, 4, 7, 9, 15}]

Out[1]=

Or display information as a chart:

In[2]:=

⨯

BarChart[{1, 2, 3, 4, 5}]

Out[2]=

There are also specialized functions for time series, financial data and much more.

Multiple datasets are automatically colored differently:

In[1]:=

⨯

ListLinePlot[{{1, 2, 3, 4, 5}, {1, 3, 7, 10, 17}}]

Out[1]=

You can change the style and appearance of plots using options like PlotTheme.

Find a curve of best fit with the Fit command:

({1,x,x²} means a quadratic fit over x.)

In[1]:=

⨯

Fit[{2, 3, 5, 7, 11, 13}, {1, x, x^2}, x]

Out[1]=

Use Show to compare the curve with its data points:

In[2]:=

⨯

Show[{Plot[%, {x, 1, 6}], ListPlot[{2, 3, 5, 7, 11, 13}]}]

Out[2]=
