平时我们用手画“条形图”的时候,常常用一条“趋势线”来表示数据的走向,在Access中,几乎任何一种二维图表,都可以添加趋势线的。

首先用鼠标激活图表的“图表区域”,然后单击“图表”菜单上的“添加趋势线”命令。就可以打开一个“添加趋势线”对话框,如下图所示,使用这个对话框就可以添加“趋势线”了。

在这个对话框上有两个选项卡,一个是“类型”,一个是“选项”,在“类型”选项卡上,有两个主要部分,“趋势预测/回归分析类型”和“选择数据系列 ”。单击“趋势预测/回归分析类型”中的一个选项,就可以在图表中画相应类型的趋势线。而单击“选择数据系列”列表框中的一项。就可以在图表中画出那个字段的数据趋势线。比如现在我们要对“总销售额”这个系列画一条“线性”趋势线的话只要先单击“选择数据系列”列表中的“总销售额”项,然后再单击“趋势预测/回归分析类型”中的“线性”图就可以了。

“选项”选项卡在“趋势线名称”中可以定义趋势线的名称。还可以在“趋势预测”中定义趋势线前推或倒退的周期数,来满足用户对趋势线的周期要求。

单击“确定”按钮,现在的图表上就出现了一条趋势线,如下图所示。

而且在一个图表上还可以添加不止几条“趋势线”,而添加的过程都和上面是一样了。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
