javascript - zoomcharts 1.5.1 - how to display multiple colors/multiple hover on a single link -

-

i want know if zoomcharts has following features in latest update (1.5.1):

i want 1 single link between 2 nodes able colored 2 colors (left-half red , right-half black). also, want able hover on these 2 different colored single-split-link differently??

if copy paste following code here, can see can't done right now...

<script>     var data = {         "nodes":[             {"id":"n1", "loaded":true, "style":{"label":"node1"}},             {"id":"n2", "loaded":true, "style":{"label":"node2"}}         ],         "links":[             {"id":"l1","from":"n1", "to":"n2", "style":{"fillcolor":"red", "todecoration":"arrow"}}         ]     };      var t = new netchart({         container: document.getelementbyid("demo"),         area: { height: 350 },         data: { preloaded: data },         info: {enabled: true, linkcontentsfunction: function(data, link, callback) {           return link.id;         }}     });  </script>

it seems right not possible split single link , hover each of parts separately.

but here "nasty" version how make using linedash , fixed node positions.

<script>         var data = {             "nodes":[                 {"id":"n1", "loaded":true, x:100, y:0, "style":{"label":"node1"}},                 {"id":"n2", "loaded":true, x:0, y:0, "style":{"label":"node2"}}             ],             "links":[                 {"id":"l1","from":"n1", "to":"n2", "style":{"fillcolor":"red", "todecoration":"arrow", "length":3}},                 {"id":"l11","from":"n1", "to":"n2", "style":{"fillcolor":"black","linedash":[100,300]}}             ]         };          var t = new netchart({             container: document.getelementbyid("demo"),             area: { height: 350 },             data: { preloaded: data },             info: {enabled: true, linkcontentsfunction: function(data, link, callback) {               return link.id;             }},             "style": {                 "multilinkspacing": 0             }         });      </script>

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
