方式一：

tf.scalar_summary(tags, values)
# ...
summary_op = tf.summary.merge_all()
logdir=os.path.expanduser("~/logs/")
summary_writer = tf.summary.FileWriter(logdir, graph=sess.graph)

summary_str = sess.run(summary_op)
summary_writer.add_summary(summary_str, global_step)

方式二：

summary_writer = tf.summary.FileWriter(LOGDIR)
summary = tf.Summary()
summary.value.add(tag="summary_tag", simple_value=0)
summary.value.add(tag="summary_tag2", simple_value=1)
#step代表橫軸座標
summary_writer.add_summary(summary, step)
