javascript - Plotly.js adds top-margin to graphs inconsistently, how to prevent it -


with plotly.js i'm getting top-margin added (not consistently), total height of graph 300px, graph 150px high. svg container stretched , actual graph smaller. can prevent white-space, , why show selectively?

margin above graph

plotly matlab syntax results in 300px div instead of 300px graph:

`% plot mean movement     data = {...       struct(...         'x', nscan, ...         'y',fastmotion, ...          'type', 'scatter')...          };     if max(fastmotion) < 0.3         yminval = 0.3;     else         yminval = round(max(fastmotion) + 1);     end     layout = struct(...     'yaxis', struct(...     'title', 'movement (mm)', ...     'range', [0, yminval]));     header{3} = 'absolute movement';     layout.width = 800;     layout.height = 300;     p = plotlyfig;      p.data = data;     p.layout = layout;     p.plotoptions.filename = 'plot_5';     html_file = plotlyoffline(p);     html_file;`

so apparently line 68 in plotlyfig.m caused issue:

obj.plotlydefaults.mintitlemargin = 80;

even though had no title, added 80 px on top of graph, maxing out @ specified graph height. setting value 0 solves problem.
