如何使用常见的jqPlot函数用于11个条形图，其中动态获取数据？
我在我的页面中使用jqPlot。我想使用11 bar graphs，条形图显示为：
六个图表：动态值显示“是”/“否”
五个图：动态值显示'优秀'/'好'/'平均'/'差'/'非常差'
每个条形图都具有从数据库中提取的动态值。
C＃代码：
[WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static void FetchGraphData(string questionId)
{
string stQuery = @"SELECT
SUM(RESPONSE2=0) AS OBJECTIVE_CLEAR_NO,
SUM(RESPONSE2=1) AS OBJECTIVE_CLEAR_YES,
SUM(RESPONSE3=0) AS ACTIVE_PARTICIPATION_NO,
SUM(RESPONSE3=1) AS ACTIVE_PARTICIPATION_YES,
SUM(RESPONSE4=0) AS QUESTIONS_ANSWERED_NO,
SUM(RESPONSE4=1) AS QUESTIONS_ANSWERED_YES,
SUM(RESPONSE5=0) AS SPEAKER_INTERACTIVE_NO,
SUM(RESPONSE5=1) AS SPEAKER_INTERACTIVE_YES,
SUM(RESPONSE6=0) AS SESSION_ON_TIME_NO,
SUM(RESPONSE6=1) AS SESSION_ON_TIME_YES,
SUM(RESPONSE14=0) AS SESSION_HELPFUL_NO,

如果可以使用简单的方法或者应该使用ajax，请告诉我。
用于绘图的jQuery示例（它具有静态值，查询中需要动态值）：
function bargraph7() {
$.jqplot.config.enablePlugins = true;
// For horizontal bar charts, x an y values must will be "flipped"
// from their vertical bar counterpart.
line1 = [[50, "very_poor"], [100, "poor"], [120, "average"], [135, "good"], [150, "excellent"]];
$.jqplot('chart7', [line1], {
seriesColors: ['#FF0000', '#FF8C00', '#FFFF00', '#32CD32', '#006400'],
seriesDefaults: {
renderer: $.jqplot.BarRenderer,
// Show point labels to the right ('e'ast) of each bar.
// edgeTolerance of -15 allows labels flow outside the grid
// up to 15 pixels. If they flow out more than that, they
// will be hidden.
pointLabels: { show: true, location: 'e' },
// Rotate the bar shadow as if bar is lit from top right.
shadowAngle: 135,
// Here's where we tell the chart it is oriented horizontally.
rendererOptions: {
barDirection: 'horizontal',
barWidth: 11,
// Set varyBarColor to true to use the custom colors on the bars.
varyBarColor: true
}
},
axesDefaults: {
tickOptions: {
fontFamily: 'Georgia',
fontSize: '10pt',
angle: -30
}
},
grid: {
drawGridlines: false,
borderColor: 'transparent',
shadow: false,
drawBorder: false,
shadowColor: 'transparent'
},
axes: {
yaxis: {
renderer: $.jqplot.CategoryAxisRenderer
}
}
});
}
我现在正在使用Page_Load中的以下语句来显示具有静态值的条形图：
Page.ClientScript.RegisterStartupScript(Page.GetType(), "PostbackClick", "bargraph7();", true);
示例条形图图像：
同样，我想使用其他条形图但使用动态值。
现在请告诉我以下内容：
1）如何使单个jQuery函数共同显示所有11个条形图，条形图id如图1，图2 .....图11？
2）我应该在jQuery / Codebehind中添加什么来显示具有动态值的条形图？

当您在StatupScript中触发方法时，您可以传递绘图的所有值，以便在加载时显示它们。
Page.ClientScript.RegisterStartupScript(Page.GetType(), "Graph",
"PlotBarGraph(" + "'chartId'" + ","
+ reader.value1 + "," + reader.value2 + ");", true);
并在js文件（客户端）中，您可以将PlotBarGraph()定义为
function PlotBarGraph(id , value1, value2) {
$.jqplot.config.enablePlugins = true;
// For horizontal bar charts, x an y values must will be "flipped"
// from their vertical bar counterpart.
line1 = [[value1, "No"], [value2, "Yes"]];
$.jqplot(id, [line1], {
seriesColors: ['#FF0000', '#006400'],
seriesDefaults: {
renderer: $.jqplot.BarRenderer,
// Show point labels to the right ('e'ast) of each bar.
// edgeTolerance of -15 allows labels flow outside the grid
// up to 15 pixels. If they flow out more than that, they
// will be hidden.
pointLabels: { show: true, location: 'e' },
// Rotate the bar shadow as if bar is lit from top right.
shadowAngle: 135,
// Here's where we tell the chart it is oriented horizontally.
rendererOptions: {
barDirection: 'horizontal',
barWidth: 11,
// Set varyBarColor to true to use
//the custom colors on the bars.
varyBarColor: true
}
},
axesDefaults: {
tickOptions: {
fontFamily: 'Georgia',
fontSize: '10pt',
angle: -30
}
},
grid: {
drawGridlines: false,
borderColor: 'transparent',
shadow: false,
drawBorder: false,
shadowColor: 'transparent'
},
axes: {
yaxis: {
renderer: $.jqplot.CategoryAxisRenderer
}
}
});
}
希望这将正常运作，你的问题将得到解决..： - ）
答案 1 :(得分：1)
仍然没有答案。 我已经做了。让我回答它，以便它可以帮助某人。
在JS文件中创建了两个函数，在codebehind中添加了一个方法。
使用Codebehind在Page.ClientScript.RegisterStartupScript中调用js函数，并在js function中传递所需的参数。
JS文件：
function barGraphWithTwoValues(id , barValue1, barValue2) {
$.jqplot.config.enablePlugins = true;
// For horizontal bar charts, x an y values must will be "flipped"
// from their vertical bar counterpart.
line1 = [[barValue1, "No"], [barValue2, "Yes"]];
$.jqplot(id, [line1], {
seriesColors: ['#FF0000', '#006400'],
seriesDefaults: {
renderer: $.jqplot.BarRenderer,
// Show point labels to the right ('e'ast) of each bar.
// edgeTolerance of -15 allows labels flow outside the grid
// up to 15 pixels. If they flow out more than that, they
// will be hidden.
pointLabels: { show: true, location: 'e' },
// Rotate the bar shadow as if bar is lit from top right.
shadowAngle: 135,
// Here's where we tell the chart it is oriented horizontally.
rendererOptions: {
barDirection: 'horizontal',
barWidth: 11,
// Set varyBarColor to true to use the custom colors on the bars.
varyBarColor: true
}
},
axesDefaults: {
tickOptions: {
fontFamily: 'Georgia',
fontSize: '10pt',
angle: -30
}
},
grid: {
drawGridlines: false,
borderColor: 'transparent',
shadow: false,
drawBorder: false,
shadowColor: 'transparent'
},
axes: {
yaxis: {
renderer: $.jqplot.CategoryAxisRenderer
}
}
});
}
function barGraphWithFiveValues(id, barValue1, barValue2, barValue3, barValue4, barValue5) {
$.jqplot.config.enablePlugins = true;
// For horizontal bar charts, x an y values must will be "flipped"
// from their vertical bar counterpart.
line1 = [[barValue1, "Very_Poor"], [barValue2, "Poor"], [barValue3, "Average"], [barValue4, "Good"], [barValue5, "Excellent"]];
$.jqplot(id, [line1], {
seriesColors: ['#FF0000', '#FF8C00', '#FFFF00', '#32CD32', '#006400'],
seriesDefaults: {
renderer: $.jqplot.BarRenderer,
// Show point labels to the right ('e'ast) of each bar.
// edgeTolerance of -15 allows labels flow outside the grid
// up to 15 pixels. If they flow out more than that, they
// will be hidden.
pointLabels: { show: true, location: 'e' },
// Rotate the bar shadow as if bar is lit from top right.
shadowAngle: 135,
// Here's where we tell the chart it is oriented horizontally.
rendererOptions: {
barDirection: 'horizontal',
barWidth: 11,
// Set varyBarColor to true to use the custom colors on the bars.
varyBarColor: true
}
},
axesDefaults: {
tickOptions: {
fontFamily: 'Georgia',
fontSize: '10pt',
angle: -30
}
},
grid: {
drawGridlines: false,
borderColor: 'transparent',
shadow: false,
drawBorder: false,
shadowColor: 'transparent'
},
axes: {
yaxis: {
renderer: $.jqplot.CategoryAxisRenderer
}
}
});
