Arrow head sizes too small about chise.js HOT 9 CLOSED

There is an open issue (cytoscape/cytoscape.js#884) for this in Cytoscape.js.

from chise.js.

Let's wait for cytoscape.js core for now

from chise.js.

Cytoscape.js will have this in version 3.1

from chise.js.

Should be done right after upgrade

from chise.js.

@ugurdogrusoz Latest cytoscape.js provides us with this feature. They expose 'arrow-scale' style property of edges for this purpose.
The default value of the 'arrow-scale' is 1 and the arrow heads seems like the following with default behaviour:

If we set 'arrow-scale' to1.5 we have the following result:

If we set it to 2 we get the following result:

Which value should be used for 'arrow-scale' style property?

from chise.js.

1.5 looks good I think

from chise.js.

Okey I set it as 1.5

from chise.js.

After we changed the default font size and related shape sizes, the view was excellent. I think now the arrowheads are too big, for example catalysis arrowhead is almost the size of the process glyph.

Right, looks like we exaggerated a bit. Decreased to 1.25 with iVis-at-Bilkent/sbgnviz.js@9275e8f.
