radarchart - min / max value
i tried to use the radar chart to display only one dataserie. Doing so i run into the issue, that the chart won't work if you provide only one or two dataseries, as the min and max values are calculated based on the values in the series.
In your sample try:
InfoViz.chart(
$('.i-radarchart2'),
'radarchart',
{
'value_fields': [ 'Repulsion Power', 'Durability', 'Hitting Sound', 'Shock Absorption', 'Control' ],
'data': [
{ 'Repulsion Power': 1, 'Durability': 2, 'Hitting Sound': 3, 'Shock Absorption': 4, 'Control': 5 },
{ 'Repulsion Power': 2, 'Durability': 3, 'Hitting Sound': 4, 'Shock Absorption': 5, 'Control': 1 }
]
},
{
'radarchart': { 'label-distance': 8, 'label-rotation': true },
'legend': { 'legend-enabled': false }
}
);
or:
InfoViz.chart(
$('.i-radarchart2'),
'radarchart',
{
'value_fields': [ 'Repulsion Power', 'Durability', 'Hitting Sound', 'Shock Absorption', 'Control' ],
'data': [
{ 'Repulsion Power': 1, 'Durability': 2, 'Hitting Sound': 3, 'Shock Absorption': 4, 'Control': 5 }
]
},
{
'radarchart': { 'label-distance': 8, 'label-rotation': true },
'legend': { 'legend-enabled': false }
}
);
to fix this issue i pass in min and max value for the radarchart:
line 2146:
for(i = 0; i < data['data'].length; ++i) {
for(j = 0; j < data['value_fields'].length; ++j) {
// provide max or min
if (data['max']) {
v_map[data['value_fields'][j]]['v_max'] = data['max'];
}
if (data['min']) {
v_map[data['value_fields'][j]]['v_min'] = data['min'];
}
item = data['data'][i][data['value_fields'][j]];
if(item > v_map[data['value_fields'][j]]['v_max']) {
v_map[data['value_fields'][j]]['v_max'] = item;
}
if(item < v_map[data['value_fields'][j]]['v_min']) {
v_map[data['value_fields'][j]]['v_min'] = item;
}
}
}
thanks for your library. was easy to use.
Supports shadow effect.
UI refine, add some shadow effect.
建议优化Demo中tip的动画效果
感觉很迟钝，给人一种效率不高的感觉，优化一下吧，我相信这肯定不是效率的问题。
最近在做的项目需要数据展示，我想用infoviz试试看。
Remove jQuery requirement
jQuery is only used in this part of code:
exports.chart = function(element, type, data, overwrite_options, callback) {
var target_id = $(element).attr('id') ? $(element).attr('id') : 'infoviz_' + core.guid();
$(element).attr('id', target_id);
var paper = Raphael(target_id, $(element).width(), $(element).height());It makes InfoViz require all jQuery library, and above part of code could easily be replaced with standard document.getElementById etc stuff.
New theme color, multipal themes.
- Add new theme color.
- Support user customized theme.
Tooltip issues
- Tooltip should not dissapear when mouse is over tooltip show point, or at least it should be configurable. Now it is not possible to have tooltips dissapear immediately (for example, 'hide-after': 100), and have them visible when mouse is over 'show point'.
- There is a bug when showing tooltips: for example, move mouse over 'China' in the first line chart. Wait for the tooltip to dissapear. Move mouse over 'China' again - tooltip will not appear again.
Combination of Charts
I'm trying to combine a stream chart, line chart & bar chart in a single view (or single canvas). I can't find any documentation on hybrid capabilities.
Can you post an example or identify if its possible?
