FusionCharts图表的画布是指在图表数据绘制的区域但不包括标题,图例和轴名称被渲染的区域。
如下图所示的蓝色区域就是图表的画布区域:
本篇教程将从四个方面教你自定义图表的画布:
1.修改画布的填充颜色
图表的画布颜色填充修饰效果如下图所示:
修改画布填充颜色用到的属性有:
属性名称 | 描述 |
canvasBgColor | 设置画布的背景颜色。 |
canvasBgAlpha | 设置画布背景的透明度。 |
数据结构如下:
JSON:
{ "chart": { "caption": "Monthly Revenue", "subCaption": "Last year", "xAxisName": "Month", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "placevaluesInside": "1", "rotatevalues": "1", "valueFontColor": "#ffffff", "canvasbgColor": "#1790e1", "canvasbgAlpha": "10", "canvasBorderThickness": "1", "showAlternateHGridColor": "0", "bgColor": "#eeeeee", "theme": "fint" }, "data": [ { "label": "Jan", "value": "420000" }, { "label": "Feb", "value": "810000" }, { "label": "Mar", "value": "720000" }, { "label": "Apr", "value": "550000" }, { "label": "May", "value": "910000" }, { "label": "Jun", "value": "510000" }, { "label": "Jul", "value": "680000" }, { "label": "Aug", "value": "620000" }, { "label": "Sep", "value": "610000" }, { "label": "Oct", "value": "490000" }, { "label": "Nov", "value": "900000" }, { "label": "Dec", "value": "730000" } ] }
XML:
<chart caption="Monthly Revenue" subcaption="Last year" xaxisname="Month" yaxisname="Amount (In USD)" numberprefix="$" placevaluesinside="1" rotatevalues="1" valuefontcolor="#ffffff" canvasbgcolor="#1790e1" canvasbgalpha="10" canvasborderthickness="1" showalternatehgridcolor="0" bgcolor="#eeeeee" theme="fint"> < set label="Jan" value="420000" /> < set label="Feb" value="810000" /> < set label="Mar" value="720000" /> < set label="Apr" value="550000" /> < set label="May" value="910000" /> < set label="Jun" value="510000" /> < set label="Jul" value="680000" /> < set label="Aug" value="620000" /> < set label="Sep" value="610000" /> < set label="Oct" value="490000" /> < set label="Nov" value="900000" /> < set label="Dec" value="730000" /> </chart>
2.自定义画布边框
默认情况下,2D图表的渲染带有画布边框。FusionChsrts允许你自定义画布边框的颜色、厚度以及透明度。带有画布边框修饰的图表如下图所示:
下表是用于自定义图表画布边框所需的属性:
属性名称 | 描述 |
showCanvasBorder | 设置为1时显示画布边框;设置为0时隐藏画布边框。 |
canvasBorderColor | 用于指定画布边框的颜色。 |
canvasBorderThickness | 用于指定画布边框的厚度。 |
canvasBorderAlpha | 用于指定画布边框的透明度。 |
数据结构如下:
JSON:
{ "chart": { "caption": "Monthly Revenue", "subCaption": "Last year", "xAxisName": "Month", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "showCanvasBorder": "1", "canvasBorderColor": "#666666", "canvasBorderThickness": "4", "canvasBorderAlpha": "80", "theme": "fint" }, "data": [ { "label": "Jan", "value": "420000" }, { "label": "Feb", "value": "810000" }, { "label": "Mar", "value": "720000" }, { "label": "Apr", "value": "550000" }, { "label": "May", "value": "910000" }, { "label": "Jun", "value": "510000" }, { "label": "Jul", "value": "680000" }, { "label": "Aug", "value": "620000" }, { "label": "Sep", "value": "610000" }, { "label": "Oct", "value": "490000" }, { "label": "Nov", "value": "900000" }, { "label": "Dec", "value": "730000" } ] }
XML:
<chart caption="Monthly Revenue" subcaption="Last year" xaxisname="Month" yaxisname="Amount (In USD)" numberprefix="$" showcanvasborder="1" canvasbordercolor="#666666" canvasborderthickness="4" canvasborderalpha="80" theme="fint"> < set label="Jan" value="420000" /> < set label="Feb" value="810000" /> < set label="Mar" value="720000" /> < set label="Apr" value="550000" /> < set label="May" value="910000" /> < set label="Jun" value="510000" /> < set label="Jul" value="680000" /> < set label="Aug" value="620000" /> < set label="Sep" value="610000" /> < set label="Oct" value="490000" /> < set label="Nov" value="900000" /> < set label="Dec" value="730000" /> </chart>
3.使用渐变填充画布
下图是带有渐变填充效果的图表画布:
下表是用于自定义图表画布渐变填充所需的属性:
属性名称 | 描述 |
canvasBgColor | 设置画布的背景颜色。 |
canvasBgAlpha | 设置画布背景的透明度。 |
canvasBgRatio | 用于指定画布背景在各个渐变的比例并以逗号分隔。 |
canvasBgAngle | 用于指定画布背景渐变的角度。 |
数据结构如下:
JSON:
{ "chart": { "caption": "Monthly Revenue", "subCaption": "Last year", "theme": "fint", "xAxisName": "Month", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "placevaluesInside": "1", "rotatevalues": "1", "bgColor": "#eeeeee,#cccccc", "canvasbgColor": "#eeeeee,#b3b3b3", "canvasbgAlpha": "100", "canvasBgRatio": "40,60", "canvasBgAngle": "0" }, "data": [ { "label": "Jan", "value": "420000" }, { "label": "Feb", "value": "810000" }, { "label": "Mar", "value": "720000" }, { "label": "Apr", "value": "550000" }, { "label": "May", "value": "910000" }, { "label": "Jun", "value": "510000" }, { "label": "Jul", "value": "680000" }, { "label": "Aug", "value": "620000" }, { "label": "Sep", "value": "610000" }, { "label": "Oct", "value": "490000" }, { "label": "Nov", "value": "900000" }, { "label": "Dec", "value": "730000" } ] }
XML:
<chart caption="Monthly Revenue" subcaption="Last year" theme="fint" xaxisname="Month" yaxisname="Amount (In USD)" numberprefix="$" placevaluesinside="1" rotatevalues="1" bgcolor="#eeeeee,#cccccc" canvasbgcolor="#eeeeee,#b3b3b3" canvasbgalpha="100" canvasbgratio="40,60" canvasbgangle="0"> < set label="Jan" value="420000" /> < set label="Feb" value="810000" /> < set label="Mar" value="720000" /> < set label="Apr" value="550000" /> < set label="May" value="910000" /> < set label="Jun" value="510000" /> < set label="Jul" value="680000" /> < set label="Aug" value="620000" /> < set label="Sep" value="610000" /> < set label="Oct" value="490000" /> < set label="Nov" value="900000" /> < set label="Dec" value="730000" /> </chart>
4.配置3D画布
在FusionCharts图表中的画布可以配置成3D效果,如下图所示。
自定义3D画布所需的属性如下表所示:
属性名称 | 描述 |
canvasBaseColor | 用于指定画布的基座颜色。 |
showCanvasBg | 设置为1(默认)时显示画布背景;设置为0时隐藏画布背景。 |
showCanvasBase | 设置为1(默认)时显示画布基座;设置为0时隐藏画布基座。 |
canvasBaseDepth | 用于设置画布基座的高度。 |
canvasBgDepth | 用于指定画布背景的深度。 |
数据结构如下:
JSON:
{ "chart": { "caption": "Monthly Revenue", "subCaption": "Last year", "xAxisName": "Month", "yAxisName": "Amount (In USD)", "theme": "fint", "numberPrefix": "$", "placevaluesInside": "1", "rotatevalues": "1", "showCanvasBg": "1", "showCanvasBase": "1", "canvasBaseDepth": "14", "canvasBgDepth": "5", "canvasBaseColor": "#aaaaaa", "canvasBgColor": "#eeeeee" }, "data": [ { "label": "Jan", "value": "420000" }, { "label": "Feb", "value": "810000" }, { "label": "Mar", "value": "720000" }, { "label": "Apr", "value": "550000" }, { "label": "May", "value": "910000" }, { "label": "Jun", "value": "510000" }, { "label": "Jul", "value": "680000" }, { "label": "Aug", "value": "620000" }, { "label": "Sep", "value": "610000" }, { "label": "Oct", "value": "490000" }, { "label": "Nov", "value": "900000" }, { "label": "Dec", "value": "730000" } ] }
XML:
<chart caption="Monthly Revenue" subcaption="Last year" xaxisname="Month" yaxisname="Amount (In USD)" theme="fint" numberprefix="$" placevaluesinside="1" rotatevalues="1" showcanvasbg="1" showcanvasbase="1" canvasbasedepth="14" canvasbgdepth="5" canvasbasecolor="#aaaaaa" canvasbgcolor="#eeeeee"> < set label="Jan" value="420000" /> < set label="Feb" value="810000" /> < set label="Mar" value="720000" /> < set label="Apr" value="550000" /> < set label="May" value="910000" /> < set label="Jun" value="510000" /> < set label="Jul" value="680000" /> < set label="Aug" value="620000" /> < set label="Sep" value="610000" /> < set label="Oct" value="490000" /> < set label="Nov" value="900000" /> < set label="Dec" value="730000" /> </chart>
