Add data to a GogBarColPlot with stacked columns

[Antonio Álvarez Feijoo <aalvarez igalia com>]

Hello,

I have been all week trying to make a GogBarColPlot with stacked columns,
but I have not been able to.

For example, I want 4 columns with two different values in each one.
With the values of X axis I don't have any problem:

   gchar ** t_legends;
   t_legends = g_new (gchar*, n_max_datetimes);
   /* ... */
   data = go_data_vector_str_new (t_legends, 4, g_free);
   gog_series_set_dim (series, 0, data, &error);

The two attempts for the columns that I have made (memory crashes...) were:

  1. gdouble *t_values_1;
     t_values_1 = g_new (gdouble, 4);
     t_values_1[0] = 20;
     t_values_1[1] = 20;
     t_values_1[2] = 20;
     t_values_1[3] = 0;

     data = go_data_vector_val_new (t_values_1, 4, g_free);
     gog_series_set_dim (series, 1, data, &error);

     gdouble *t_values_2;
     t_values_2 = g_new (gdouble, 4);
     t_values_2[0] = 50;
     t_values_2[1] = 50;
     t_values_2[2] = 0;
     t_values_2[3] = 30;
     data = go_data_vector_val_new (t_values_2, 4, g_free);
     gog_series_set_dim (series, 2, data, &error);


  2. gdouble *t_values_1;
     t_values_1 = g_new (gdouble, 4);
     t_values_1[0] = 20;
     t_values_1[1] = 20;
     t_values_1[2] = 20;
     t_values_1[3] = 0;
     t_values_1[4] = 50;
     t_values_1[5] = 50;
     t_values_1[6] = 0;
     t_values_1[7] = 30;
     data = go_data_vector_val_new (t_values_1, 4, g_free);
     gog_series_set_dim (series, 1, data, &error);


Sorry, but I am learning to use libgoffice and I am a little lost...

Thanks.
