图表的背景是指图表绘制的整个地区,由图表边框包围。这篇教程将从四个方面教大家配置图表的边框和背景。
FusionCharts的2D图表有一个默认的边框,而3D图表没有,但你可以设置一个。2D图表的自定义边框如下:
下表是自定义图表边框的一些属性及简要说明:
属性名称 | 描述 |
showBorder | 用来指定是否要显示边框。属性值为1时显示;属性值为0时不显示。 |
borderColor | 用来指定边框的颜色。 |
borderThickness | 用来指定边框的厚度。 |
borderAlpha | 用来指定边框的透明度,从0到100。0表示完全透明,100表示完全不透明。 |
使用这些属性来自定义图表边界所需的数据结构如下:
JSON:
{ "chart": { "caption": "Monthly Revenue", "subCaption": "Last year", "xAxisName": "Month", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "showBorder": "1", "borderColor": "#666666", "borderThickness": "4", "borderAlpha": "80", "theme": "fint" }, "data": [ { "label": "Jan", "value": "420000" }, { "label": "Feb", "value": "810000" }, { "label": "Mar", "value": "720000" }, { "label": "Apr", "value": "550000" }, { "label": "May", "value": "910000" }, { "label": "Jun", "value": "510000" }, { "label": "Jul", "value": "680000" }, { "label": "Aug", "value": "620000" }, { "label": "Sep", "value": "610000" }, { "label": "Oct", "value": "490000" }, { "label": "Nov", "value": "900000" }, { "label": "Dec", "value": "730000" } ] }
XML:
<chart caption="Monthly Revenue" subcaption="Last year" xaxisname="Month" yaxisname="Amount (In USD)" numberprefix="$" showborder="1" bordercolor="#666666" borderthickness="4" borderalpha="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>
图表的背景就是边框里面的所有区域,2D图表的自定义背景颜色如下图所示:
下表是用于自定义图表背景的属性:
属性名称 | 描述 |
bgColor | 用于指定图表的背景颜色。 |
bgAlpha | 用于指定图表背景的透明度。 |
自定义图表背景所需的数据结构如下:
JSON:
{ "chart": { "caption": "Monthly Revenue", "subCaption": "Last year", "xAxisName": "Month", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "canvasBgAlpha": "0", "bgColor": "#DDDDDD", "bgAlpha": "50", "theme": "fint" }, "data": [ { "label": "Jan", "value": "420000" }, { "label": "Feb", "value": "810000" }, { "label": "Mar", "value": "720000" }, { "label": "Apr", "value": "550000" }, { "label": "May", "value": "910000" }, { "label": "Jun", "value": "510000" }, { "label": "Jul", "value": "680000" }, { "label": "Aug", "value": "620000" }, { "label": "Sep", "value": "610000" }, { "label": "Oct", "value": "490000" }, { "label": "Nov", "value": "900000" }, { "label": "Dec", "value": "730000" } ] }
XML:
<chart caption="Monthly Revenue" subcaption="Last year" xaxisname="Month" yaxisname="Amount (In USD)" numberprefix="$" canvasbgalpha="0" bgcolor="#DDDDDD" bgalpha="50" 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>
当时用渐变来填充图标背景时,你需要配置以下三个方面:
2D图表的渐变填充背景如下图所示:
下表是自定义填充背景所需的属性:
属性名称 | 描述 |
bgColor | 用于指定背景颜色。 |
bgAlpha | 用于指定每种颜色的透明度。 |
bgRatio | 用于指定渐变中每种颜色的比例。 |
自定义渐变填充背景所需数据结构如下:
JSON:
{ "chart": { "caption": "Monthly Revenue", "subCaption": "Last year", "xAxisName": "Month", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "canvasBgAlpha": "0", "bgColor": "EEEEEE,CCCCCC", "bgratio": "60,40", "bgAlpha": "70,80", "theme": "fint" }, "data": [ { "label": "Jan", "value": "420000" }, { "label": "Feb", "value": "810000" }, { "label": "Mar", "value": "720000" }, { "label": "Apr", "value": "550000" }, { "label": "May", "value": "910000" }, { "label": "Jun", "value": "510000" }, { "label": "Jul", "value": "680000" }, { "label": "Aug", "value": "620000" }, { "label": "Sep", "value": "610000" }, { "label": "Oct", "value": "490000" }, { "label": "Nov", "value": "900000" }, { "label": "Dec", "value": "730000" } ] }
XML:
<chart caption="Monthly Revenue" subcaption="Last year" xaxisname="Month" yaxisname="Amount (In USD)" numberprefix="$" canvasbgalpha="0" bgcolor="EEEEEE,CCCCCC" bgratio="60,40" bgalpha="70,80" 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>
你也可以使用外部图像(只能是GIF、JPEG或PNG)作为图表的背景,如下图所示:
使用外部图像作为图表背景涉及属性如下表所示:
属性名称 | 描述 |
bgImage | 用于指定图表背景图片的URL。 |
设置外部图片作为图表背景的数据结构如下:
JSON:
{ "chart": { "caption": "Top 3 Juice Flavors by sales", "subCaption": "Last year", "xAxisName": "Flavor", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "canvasBgAlpha": "0", "showAlternateHgridColor": "1", "bgImage": "//upload.wikimedia.org/wikipedia/commons/7/79/Misc_fruit.jpg", "bgImageAlpha": "40", "bgImageDisplayMode": "stretch", "theme": "fint" }, "data": [ { "label": "Apple", "value": "810000" }, { "label": "Cranberry", "value": "620000" }, { "label": "Grapes", "value": "350000" } ] }
XML:
<chart caption="Top 3 Juice Flavors by sales" subcaption="Last year" xaxisname="Flavor" yaxisname="Amount (In USD)" numberprefix="$" canvasbgalpha="0" showalternatehgridcolor="1" bgimage="//upload.wikimedia.org/wikipedia/commons/7/79/Misc_fruit.jpg" bgimagealpha="40" bgimagedisplaymode="stretch" theme="fint"> < set label="Apple" value="810000" /> < set label="Cranberry" value="620000" /> < set label="Grapes" value="350000" /> </chart>
FusionCharts还允许你对图表背景图片进行自定义操作:
部分透明背景的2D图表如下图所示:
下表是自定义图表背景图像所需的属性:
属性名称 | 描述 |
bgImage | 用于指定图片的URL。 |
bgImageAlpha | 用于指定图片的透明度。 |
bgImageVAlign, bgImageHAlign | 用于指定图像的水平和垂直对齐方式。 |
bgImageScale | 用于放大或缩小图像的比例。 |
bgImageDisplayMode | 用于指定图像的显示模式。 |
自定义背景图片透明度的数据结构如下:
JSON:
{ "chart": { "caption": "Top 3 Juice Flavors", "subCaption": "Last year", "xAxisName": "Flavor", "yAxisName": "Amount (In USD)", "numberPrefix": "$", "canvasBgAlpha": "0", "showAlternateHgridColor": "1", "bgImage": "//upload.wikimedia.org/wikipedia/commons/7/79/Misc_fruit.jpg", "bgImageAlpha": "25", "bgImageDisplayMode": "stretch", "theme": "fint" }, "data": [ { "label": "Apple", "value": "810000" }, { "label": "Cranberry", "value": "620000" }, { "label": "Grapes", "value": "350000" } ] }
XML:
<chart caption="Top 3 Juice Flavors" subcaption="Last year" xaxisname="Flavor" yaxisname="Amount (In USD)" numberprefix="$" canvasbgalpha="0" showalternatehgridcolor="1" bgimage="//upload.wikimedia.org/wikipedia/commons/7/79/Misc_fruit.jpg" bgimagealpha="25" bgimagedisplaymode="stretch" theme="fint"> < set label="Apple" value="810000" /> < set label="Cranberry" value="620000" /> < set label="Grapes" value="350000" /> </chart>
