9This is another example implementation but it might be handy for simple cases of
10presenting results. Of course one can debate the usefulness of certain ways of
11presenting but here we avoid that discussion. Lets start with a simple pie
12chart (\in {figure} [chart:1]).

16 draw lmt_chart_circle [

30As with all these \LMTX\ extensions, youre invited to play with the parameters.
31in \in {figure} [chart:2] we see a variant that adds labels as well as one that
32has a legend.

48The styling of labels and legends can be influenced independently.

81A second way of rendering are histograms, and the interface is mostly the same.
82In \in {figure} [chart:3] we see two variants
83
84\startbuffer[3a]
85\startMPcode
86 draw lmt_chart_histogram [
87 samples = { { 1, 4, 3, 2, 5, 7, 6 } },

110and one with two datasets:

133\stopMPpage

136A cumulative variant is shown in \in {figure} [chart:4] where we also add a
137background (color).

145A different way of using colors is shown in \in {figure} [chart:5] where each
146sample gets its own (same) color.
147
148\startbuffer[5]
149\startMPcode
150 draw lmt_chart_histogram [

170As with pie charts you can add labels and a legend:
171
172\startbuffer[6a]
173\startMPcode
174 draw lmt_chart_histogram [
175 height = 6cm,
176 samples = { { 1, 4, 3, 2, 5, 7, 6 } },
177 percentage = true,
178 cumulative = true,
179 trace = true,
180 labelstyle = "ttxx",

184 ] ;
185\stopMPcode
186\stopbuffer
187
188\typebuffer[6a][option=TEX]
189
190The previous and next examples are shown in \in {figure} [chart:6]. The height
191specified here concerns the graphic and excludes the labels,
192
193\startbuffer[6b]
194\startMPcode
195 draw lmt_chart_histogram [

204 labelcolor = "black"
205 labelstyle = "bfxx"
206 legendstyle = "tfxx",

225The third category concerns bar charts that run horizontal. Again we see similar
226options driving the rendering (\in {figure} [chart:7]).
227
228\startbuffer[7a]
229\startMPcode
230 draw lmt_chart_bar [
